(6) Clear-ing the rank vegetationin the immediate vicinity of dwellings and settle-ments, so as to destroy the shelter for such mosqui-toes as may find their way to the vicinity of thehouses; to hasten evaporation and the drying ofsmall water collections and marshy places; to exposeto view small breeding places and to remove thetemptation to throw water containers into thevegetation. These measures, conscientiously and painstak-ingly carried out, resulted in reducing the number ofmalaria cases treated in the hospitals from percent of the working force per month in 1906 to OLD CHURCH AT TABOGA The square box on the corner of the wall contains the mummied head of a favorite priest per cent of the working force per month in 1911,and the death from malaria among employees from233 in 1906 to 47 in 191i. The malaria sick rate for 1906, if continued to1911, would give, on the basis of the number ofemployees in 1911, about 40,000 cases of malariasick in the hospitals for the year, or a loss in laborof about 200,000 days of work. The total numberof employees sick in hospitals with malaria in 1911was 8946—or a loss of 44,730 days of work. A gainof about 155,000 days was, therefore, made. Placingthe loss to the Government for each days labor, plus treatment, at therather low figure of $3per man, the gain inthis one item of savingmore than offset thecost of sanitation prop-er. These figures donot include malarialcases treated in the dis-pensaries and in this class of pa-tients the gain has un-doubtedly b
